Controls lose data binding when added to cluster

Question

Please forgive me if this is a newbie question, but I can't seem to find an answer.
In a nutshell, I have an array (constant) of strings and a cluster of booleans.  I want to search the name of each boolean in the cluster for a match to a string in the array and perform an action for each match.  Say I want to turn on all booleans that match.
The problem is that the booleans are bound by datasocket - to OPC server to PLC.  So when I add a boolean to the cluster, the data binding is dropped.  Attempts to reassign data binding are unsuccessful.  If I move the control outside the cluster and reassign data binding, it works.  There are a fair number of booleans so I want to avoid wiring them one by one.
I am using LabVIEW 8.6 and there is a known bug similar to this for arrays of fixed size.  However I don't totally understand the solution and how I would apply it to a cluster:  "Uncheck autopreallocate arrays and strings in the VI properties execution category for all VIs not intended to run on an FPGA."  There is no listing for clusters.  Could I be doing something wrong?  Should I be using shared variables instead of data binding?

Return
DataSocket and Fixed Size Array Do Not Work
You cannot use front panel DataSocket data binding with fixed-sized arrays.
Workaround: Uncheck autopreallocate arrays and strings in the VI properties execution category for all VIs not intended to run on an FPGA.

Peter,
Thanks. i will separate this in 3 questions.
I posted the whole thing, so people could copy the code on
Flex and tested to see what I am talking about.
"evt.target.selectedItem should be a <module> element.
Is that not happening?"
Yes, when loading is a module. Once a click on a list item I
get the following error:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.

If a click dismiss all, I can click on the tabs and the
content on the list changes as expected, but when clicking on the
list items, they don't work.
If a click on the video tab the state changes, but I have to
click on the list twice to play a video. After that I the list
items for the other tabs work.
